The name of the Unit.
The model of the Unit.
The number of input and output points provided by the Unit.
The type of terminal block and connector that is used for connecting the Unit.
The I/O refreshing methods that are used by the Unit. Free-Run refreshing and syn-
chronous I/O refreshing are available.
The polarity of the output devices that are connected to the Unit. NPN connection
and PNP connection are available.
The rated output voltage of the Unit.
The output load voltage range of the Unit.
The maximum output load current of the Unit. The specifications for each output
point and for the Unit are described.
The maximum allowable inrush current of the Unit. Any inrush current from an exter-
nal connection load must be kept to or below this value.
The leakage current when the output of the Unit is OFF.
The residual voltage when the output of the Unit is ON.
The delay time for which data in the internal circuit is reflected in the state of output
elements of the Unit. It is described according to the ON/OFF sequence.
The polarity of the input devices that are connected to the Unit. NPN connection and
PNP connection are available.
The rated input voltage and range of the Unit.
The input current at the rated voltage of the Unit.
The input voltage in which the Unit input turns OFF, and corresponding input current.
The delay time for which the status change of the input terminals reaches the inter-
nal circuit of the Unit. The input filter time below is not included. It is described
according to the ON/OFF sequence.
The filter time when the status of the internal circuit is read as the data to the internal
of the Unit. It is same for both ON/OFF. The filter time to be set by the Support Soft-
ware is described.
The type of indicators on the Unit and the layout of those indicators.
The dimensions of the Unit. They are described as W x H x D. The unit is "mm".
The isolation method of the I/O circuits and internal circuit of the Unit.
The insulation resistance between the I/O circuits and internal circuit of the Unit.
The dielectric strength between the I/O circuits and internal circuit of the Unit.
The method for supplying I/O power to the Unit. The supply method is determined
for each Unit. The power is supplied from the NX bus or the external source.
The current capacity of the I/O power supply terminals (IOV/IOG) of the Unit. Do not
exceed this value when supplying the I/O power to the connected external devices.
The power consumption of the NX Unit power supply of the Unit. The power con-
sumption when NX Units are connected to a CPU Unit and the power consumption
when NX Units are connected to a Communications Coupler Unit.
The current consumption from I/O power supply of the Unit. The load current of any
external connection load, input current, and current consumption of any connected
external devices are not included.
The weight of the Unit.
The circuit layout of the I/O circuits of the Unit.
The installation orientation of a CPU Unit containing the Unit and the installation ori-
entation of a Slave Terminal containing the Unit. Any restrictions to specifications
that result from the installation orientation are also given.
